About Star Products (Lang Tools)
Star Products, widely recognized in the professional automotive tool industry under the combined identity of Lang Tools (Star Products), has built a long-standing reputation as a manufacturer of precision diagnostic and testing equipment. From independent repair shops to dealership service bays, technicians have relied on Star Products tools to accurately assess engine health and fuel system performance — the kind of work where guesswork simply isn't an option.
At the core of the Star Products lineup is a commitment to accuracy, durability, and broad vehicle coverage. Their tools are engineered to work across a wide range of domestic and foreign platforms — gasoline and diesel alike — making them a versatile choice for professional technicians who encounter a variety of vehicles every day.
Engine Compression Testing
Star Products is perhaps best known for their Engine Compression Test Kits. These kits are designed to measure cylinder pressure with precision, helping mechanics quickly identify issues such as worn piston rings, leaking valves, or compromised head gaskets. Star Products' compression testers are available for both gasoline and diesel engines, with models like the TU-30A featuring dual-scale gauges (0–300 PSI / 0–21 bar) and a comprehensive set of adapters — including a patent-pending Ford Triton engine adapter — to ensure compatibility across virtually all major engine families.
Fuel System Diagnostics
Beyond compression, Star Products offers a well-rounded suite of fuel system tools. Their Fuel Injector Tools and Fuel Injector Testers allow technicians to evaluate injector function and diagnose fuel delivery problems with confidence. Complementing these is a dedicated Fuel Tester designed for quick, reliable checks of fuel system integrity — an essential step when diagnosing driveability complaints or lean/rich condition codes.
Oil Pressure Diagnostics
Rounding out the diagnostic toolkit, Star Products' Engine Oil Pressure Tester Kits give technicians the ability to verify oil pressure readings with shop-grade accuracy. Models like the TU-16A are designed to test both engine oil and automatic transmission pressure, offering quick-change fittings for efficient workflow in busy service environments.
